Three rigid bodies (Nodes 2, 3, and 4) are connected by five
springs as shown below. Assume that the
bodies can only undergo translation in the horizontal direction.
Horizontal force P2=1000 N and
P4=1500 N is applied to Elements 2 and 4, respectively. The spring
constants in (N/mm) are given as:
k1=400, k2=500, k3=600, k4=100, and k5=300. Nodes 1 and 5 are
fixed. Determine the nodal
displacements and reaction forces at the walls.

UIT LE 11/4., /4.127 Three rigid bars with the same length L are pinned as shown in the figure. They are connected by linear springs with the same spring constant K. A downward force P is applied at the point F. Use the principle of virtual work to determine the vertical displacements at points A, C, and F corresponding to the equilibrium state. Assume that all displacements are small at the equilibrium state.
